Application filed January 17, 1907.

T 0 all whom it may concern:

Be it known that I, LINDSLEY Sonar- MOES, residing at New Yorlr, in the county of New York and State of New York, have invented certain new and useful Improvements in Lamps, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to illuminating ap aratus generally, iut, as it more particuiarly concerns gas lighting apparatus comprising a cluster of separate lamps, it will be conducive to clearness to disclose it in such connection.

One object of this invention is to provide an illuminating apparatus of the class described, wiich will comprise a plurality of suitably incased lamps which by a simple and inexpensive means are maintained against relative movement.

Another object is to provide a gas lighting apparatus comprising a number of distinct lamps each capable of being regulated in luminosity independently of its companions, together with a globe support and means for so bracing the upper ends of said lamps to the said support that relative movement of the parts will be prevented.

Another object is to design an illuminating apparatus peculiarly adapted for the employment of a cluster of individually controlled gas lamps of the inverted mantle type, and in which the cluster will be ri 'idl y held within a casing adapted to effectlvely dispose of the products of combustion, to insure a steady burnin of the lamps, and, if desired, modulate and evenly distribute the light of the cluster.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

Referring now to the accompanying drawings, wherein is illustrated one of the various possible embodiments of my invention, Figure 1 is a sectional elevation illustrating an embodiment of certain of the various features constituting this invention and show- Specificiation of Letters Patent.

ing the preferred combination and arrangement thereof; Fig. 2 is a horizontal section taken along line 22 of Fig. l to more fully show certain details of this embodiment.

The accompanying drawings show this invention as employed in connection with the illuminating of railway cars, in which the apparatus as a whole is suspended from the roof 1 of such cars. The casing or support designated by 2 may be provided with a flaring crown-piece 3 which is affixed to such roof in any suitable manner, and at its lower end such casing or support carries a globe 4 which, as shown, is inverted, and being spherical in form serves as a means for not only protecting the inclosed cluster of indi vidually controlled lamps, but also is adapted to evenly diffuse and modulate the light emitted therefrom. To facilitate the cocoasional displacement of the globe for the purpose of gaining access to the cluster, a swing ing ring 22 may be hinged to the support, and the globe may be secured directly to such hinged ring. A latch 23 serves to hold closed the ring.

This invention proposes to arrange within the casing and globe a plurality of independent lamps 5, 6, 7 and 8, w rich may be sus pended from the roof in any desirable manner. These lamps will preferably be symmetrically disposed to form an ornamental cluster and in order that the light emitted may be as evenly distributed as possible.

While each of the aforesaid lamps may be supported in various ways, the shown manner of so doing will ordinarily be regarded as preferred and will be found to be essentially simple though exceedingly effective. To this end this invention utilizes the conduits 9, which are primarily for the purpose of conveying the gas which will ultimately be burned in said lamps. Such conduits are .vertically disposed and are suspended from their upper ends, which are in communication with supply pipes 10 leading from the source of gas, which may be common to all and may consist of a suitable tank underlying the cars. he lamps are fixed to the lower ends of these conduits so as to receive the gas therefrom and at the same time be carried thereby. The roducts of combustion will ascend througi the upper part of the casing or support which constitutes a chimney, and both for convenience of arrangement and for economys sake the conduits may extend through such chimney.

Inasmuch as it is desirable to have an individual control for each lamp in order that one or more of said lamps may be used simultaneously, each of the conduits will be provided with a suitable cock 11, which may conveniently be arranged at the upper end of the same, as shown on the drawing. These cocks may each comprise a bot y portion 12 to which the end of the supply pipe 10 is secured, and a lead 13 may extend laterally and be secured to the upper portion of the associated conduit, which is bent outwardly for this purpose. This arrangement pre vents excessive heating of the cocks and at the same time affords a very accessible location for such cocks. The turnin or finger grip of each cock will preferably lie exterior of the support or casing, or at least be so disposed as to be readily grasped, either manually or by means of a suitable wrench.

A spider 14 of any suitable form is in engagement with and maintains the lamps against excess vibration, such spider being in turn secured to an adjacent portion of the casing 2. In the specific iorm shown, such spider is integral and is composed of a number of portions 15 which are interposed between each pair of lamps and are poiygonally arranged. Hubs 16 are formed in the spider, and these hubs circumscribe the lower ends oi the conduits or the upper ends of the lamps, as the case may be or as the points of attachment may be dii'lerently expressed although equivalent in fact, so as to prevent any lateral movement of the latter. Thus While I have, for convenience description, stated that the spider is in engagement with the conduits adjacent the lamps, it is to be understood that I also contemplate, in an equivalent sense, an engagement with any other suitable part oi the lamps. Integrally extending from these hubs are arms 17 which at their outer ends 18 are secured to a part oi the casing 2, which may consist of a flange 19 which inturns from the bottom of said casing.

It will be understood, in view of the loregoing explanation, that the products of combustion from the lamps may rise upwardly without meeting any obstruction due to the spider, and may pass through the upper portion of the casing 2, which serves as a chimney, and thence into the ventilator 20, from which such products will ultimately escape. Fresh air for admixture with the gas may be obtained through the perforations 21 in the body portion of the casing, or the mixing may take place externally oi the chimney or casing 2, as desired.

It will thus be understood that this invention is one well adapted for attaining the various objects and ends set forth in the foregoing.

The lamps are each capable of being indi vidually regulated or controlled, and one or more of said lamps may be employed at a time, as desired. Moreover, because of the peculiar system of bracing the lamps, it will be noted that they are prevented from rocking or swaying under the motions of a car while in transit, and that the whole arrangement is simple and essentially practicable in nature.
